深紅の刃を持つダークサイバーエルフ

A dark ultra-detailed anime cyber-gothic portrait of a {argument name="character type" default="female elf warrior"} in a three-quarter side profile, framed from upper thighs to head, standing in a ruined futuristic industrial city. She has a short blunt bob in {argument name="hair color" default="silver-white"}, pale skin, long sharp elf ears, and a calm cold expression with one visible glowing {argument name="eye color" default="crimson red"} eye. Her hair is windswept across her face, and she wears a black star-shaped metallic hair ornament near one temple. Outfit is a sleek black biomechanical armored dress with glossy obsidian surfaces, spiked and layered plates, torn lace-like textures around the shoulders and chest, and intricate demonic exoskeleton detailing. One arm is heavily armored into a massive organic-mechanical gauntlet. She holds or merges with an enormous jagged living sword crossing diagonally from the lower left foreground toward her torso; the blade is black metal with glowing veins, embedded red cores, and violent molten energy bursting through it like liquid fire. Red energy ribbons, sparks, smoke, and ember-like particles swirl around her body and weapon. The background is a vertical dystopian megastructure filled with black steel towers, cables, hanging chains, fragments of red holographic code, occult-tech insignias, and faint industrial symbols, all mostly swallowed by shadow. Use a black and deep crimson palette with extreme contrast, glossy highlights, sharp rim light, dramatic backglow behind the head, dense detail, chaotic painterly effects, and a grim apocalyptic atmosphere. Composition should feel like premium dark fantasy key art, highly polished, cinematic, intimidating, elegant, and explosive.
